Here's what my stack looks like at the point of failure:
#0 0x00007ffff293a2ae in auditsimdelete (jt=0x7ffff1438200,

The line number for plusXX in vx.c will be one greater than the line
number in the gmp-redo-messy branch, because I have added a line
immediately before it:
366 {if(MEMAUDIT&2)audittstack(jt);}
367 void *previous= *z;
368 *z++= jtxplus(jt,(u),(v));
369 {if(MEMAUDIT&2)audittstack(jt);}
The value of previous (and of *z) is 0. So, my thought in adding that
line was useless, because the error happens before *z gets updated and
before z gets updated.
As best as I understand it, the only difference between line 366 here
and the first line of jtxplus is the creation of a new stack frame for
the jtxplus invocation.
(And, I'm having difficulty reasoning about how that could cause
audittstack to fail...)
